TO LL WHOM4 IT MAY CONCERN:

Be it Known that we, N. H. SHERBURNE, of Elgin, in the county ,of Kane,and State of Illinois, and JAMES T. WHIPPLE, of Chicago, in the countyof Cook, and State aforesaid, have invented a certain new and use'i'ulImprovement in Well Tubing; and we do hereby declare that the followingis a full and exact description gf the constructionv and operation ofthe same, reference being had to the accompanying drawings, and to theletters of reference marked thereon, making a part of thisvspecification, in which- Figure 1 is a perspective view. i

Figure 2 is a verticalsection through the same, with its parts adjustedand screen attached, showing the relative position of each whencomplete.`

Figure' is a vertical section through the same, showing the relativeposition of the tubes (as regards the perforations therein,) as the sameis driven into the ground.

Figure 4 is a transverse section on lines vk.

Figure 5 is a section of the rod employed in adjusting the screen.

Figure 6 is a view of the screen detached. v

Similar letters of reference as they 'occur in the several` figuresdenote like parts in each of the drawings.

Our invention relatesto an improvement in that class of wells which isformed by sinking or driving a metallic tube or pipe into the ground toany given distance, that is to say, until a course of water is reachedwhich will `furnish the required amount, thus avoiding the great amountof labor and expense of sinking and finishing the common well; and thenature of our improvement consists- I First, in attaohing'or'suspend-ingto the bottonroi` the mainpipe externally a short sectionoi` pipe orhollow cylinder to which the point is attached, the sine of cavity insaid cylinder being such as to allow the main pipe to pass down throughthe same, and thus bring the lower end ofthe pipe in contact with oragainst the upper end of the point, said cylinder and the lower end ofsaid pipe being perforated transversely, and so arranged that asthelpipe is forced down through the cylinder the perforations in one areirmlyiolosed by the solids ofthe other, thus preventing the earth, sand,or any like substance from filling the'pipe while being driven, but byslightly adjusting or tilting the main pipe upward the perforations inboth are opened, thus allowing a free ingress of Water.

Second, inserting at the bottom of they main pipe, and within saidcylinder, -a screen or l-ter, in the manner and ofthe form ofconstruction hereinafter more fully explained. I

To enableothers skilled in the art to construct and use our invention,we will proceed tordesoribe the same with reference to the drawings. n

A represents the main pipe, which is of iron, and having acavitytherein, from one and a quarter inch to two inches in diameter, as maybe required; said pipe being formed in sections from four to six feet inlength, and coupled one to the other by means of a socket S, Awhich isprovidedwith a thread internally which takes into a like thread upon theoutside of the pipe. At the bottom of the rst section of said' pipe weattach a collar or flange, C, which is shrunk around the end of thcsaine, and the end of the pipe riveted or upset, or may be attached byany equivalent means that will insure the required amount of strength.From the lower end of this pipe we attach or suspend asecond shortsection of pipe, or, vin otherwords, a cylinder, B, which is alsoprovided with alike flange, C, internally attached at tho top, and soarranged as to rest orbe suspended upon ange C of the main pipe, thecavity in said cylinder' being of sutlicient size to admit of the mainpipe passing down through the same and resting upon the upper end orshank ofthe point, which is attached to the lower end of said cylinderby means of n. thread cut therein, which takes into a like thread uponthe shank of the point. We provide the `lower end of pipe A with seriesc? periolations, the same passing through'and in a horizontal line roundthe pipe, and of equal distance one from the'other. Said cylinder, B, isalso provided with like series of perforations, of equal or graduateddistance ono from thc other, and so arranged, as regards the distancefrom the point upward, as to bring the pcrforations n the one againstthe solid or the other, as the main pipe is forced down through thecylinder while being driven' into the ground, as is shown by iig. 3. Weinsert within the cavity. of said cylinder a fiat or dish-shaped pieceof iron, L, which rests upon the upper end of the shank of thc point,its size being such as to be capable Iof Vertical adjustment, or, inother words, admits of itbeing drawn up from the bottom through the pipeand cylinder by means of a part ot the same protruding up'ward from thecentre in a cone-like shape, which is provided with a thread externallythat takes into `a like thread within the socket attached 'to the lowerend of rod K, (when the same is applied for the purposefof withdrawingsaid disk.) We also insertwithin said pipe and cylinder a screen, m,which is formed of perforated tin, or of any equivalent metallicsubstance, its length being such as hto extend from the first or upperseries of perforations i-n pipe A, downward the entire length ofcylinder B, and thus be supported by resting upon the end of the upwardprotruding part of disk L; the size of said screen `at the upper endbeing such as to closely ill thecavity in the main pipe, the lower endof the samev bein g less in size, laterally, near 'one-halt` its length,which forms a vacant space of from on e-half inch to three-quarters ofan inch in diameter round the screen `between its sides and the sides ofthe cylinder.

u The objects of ythis style of arrangement are several first,the-cylinder being suspended to the main pipe, and the lines ofperforations in the one being so arranged as to come against the solidof the other, thus excluding the earth while being driven; second,should the water be found in quicksand, the vacant space formed betweenthe screen and cylinder Iwill fill with the coarser particles of sand,the nerpassing through the screen until said vacant space is filled,which then forms a lilt'er, and nothing but the pure water'will passthrough into the pipe -and third, should the water be found in clay, asis often the case, there will be a sediment settle in the pipe andscreen; for removing this, we withdraw the screen by means of rod K,draw disk L up through the pipe by means of sa'id rod, thus removing thesediment therefrom; replace the several parts and the well is asclear aswhen new.

The plan of sink-ing our tubing and its operation' are as follows:Cylinder B being attached or suspended to pipe A, in the manner hereindescribed, point n is then attached and the pipe placed'in a verticalposition allowing the pipe to pass down through the cylinder, and thelower end rests upon the shank of the point. The rst section is driven,a second is -tlien attached by means of socket S, and so on until therequired denth is attained. The main pipe is then drawn up the lengthofthe cylinder, which opens the perforations in each; a pump is thenattached to the upper end of the pipe,`and a cavity formed round thecylinder for the water to collect, by means of pumping up the sandandgravelv through the pipe; screen m is then inserted from the top bymeans of rod K, allowing said screen to pass vdown through the cavity inthe pipe and the lower end of the same to rest upon disk L; the pump isthen again attached.A andthe well is completed.

We are aware that a patent was granted to John H. Duch and James T.Whipple, for an improvement in well tubing, wherein the screen issuspended within the main pipe by means of flanges thereon, but such wedo not claim. v l l l Having fully 'described the nature and eifect ofkour invention, what we claim as new, and desire to securegby LettersPatent, is`- The combination of cylinder B, pipe A, screen m, andthedisk L, the whole constructed, arranged, and operated substantiallyin the manner and for the purpose described.
